TRAP.

SPECIFIGA'IIION forming part of Letters Patexxt N0. 272,020, d.ated February 13, 1883,

Applicatinn filed J uns 8, 1882.

T0 all whom 1It mag; co-ncern Bo il: known that; I, JOSEPH BENNOR, a oiti zen of 13118 United Stabes, residing at Philadelphia, in the county of Pbiladelphia und State ot' Ponnsylvania, have invonted oertain new and useful Improvements in 'l1aps for Wash- Basins, &o., of whioh tl1e followiug is a specifioatiou, reference being had therein to the acoompanying drawings, wherein Figure l is a vertical longitudinal seotion of a trap ombodyi ng my inventiori. Fig. 2 is a Figs. 3 and 5 ropresent sootional views oft the elas'tio valve, wibh modified forma of weight or load therefor. Fig. 4 is a plan illustrating the manuer ofinserting a split; washer in tho elastio valve. Fig. 6 is an elev-ation ot' the trap, am]. Fig. 7 is a vertioal seetion of a modified construotion of same.

My in vention has relation to traps fo1 bathtubs, lavatories, &c. and has for its object 130 provide a trap the parts of which arsimple in 00I1St1fucti0n und oan be readily' put togeth1r anti diseonneote'd, am the trap be expedit iously connected to the wasto-pipes of wash-basins, &c., withou ohanging the size or the location of said pipes.

My inyen'nion aocordingly eonsists of a trap comprising a ohamber having eduction und induction pipes, and an elastio ba1l or valve suitably weighted or provided With a load whioh is of a siZe that it prewants the valve being forced into tho seat or pipe iuteuded to be sealod thereby, said. valve being designed und. adapted to descond by gravity 130 seal the out;leb of tho induotion-pipe, und is mised therefrom to unseal said outlel; by hydrostatic pressuro in the induotion-pipe.

Referring 110 tho accompanying drawings, A repr(2sents a trap composed of a glass or metal body, B, bottom B, and -top B with in terposed gaskets or packing-rings b b to form air-tight joints betWeen said parts.

C-represents a. yoko having a, stud, c, at one end and a sorew, o, a1: its opposito end. Said stud and the und of the sorew c enter openings 12 b in the bobtom und top plates, B B, gzspeotively, so that; by turning or adjusting screw c all of said parts are rigidly and seoi1rely held together in their due am] relative position. By discounecting the yoke 0 the parts of the trap may be readily taken apart I'or cleansing purposes. Tho top plgxte, B is (N0 model.)

provided with an ednobion-pipe, D, the ed;:o d ot which may be beveled oft, as shown in Fig. l. The bottom plate, B, is formed 0x providecl with an induotiompipe,D. The edge of it;s outlet d is suit-ably beveled or turned ofl' to form a seat, 0P, for an elastio Dali or valve, E, whioh rests thereon to seal said outlet. The valvo E is dosigned m be made of soft rubber, in order that it may possess extreme elastici ty so that when in position on seat; 01 ooutact will be made therewith throughout the entiro area of said seat 130 form a perf'eol; seal therefor. 'The fo rmation of such seal between valvo E und seat 01 is further assured by the em ploymenb 0f a weighi; or load, F, plaoed With in said valve. Such weight may consisl; of u cury, shot, o1 other suitable materia'l may bo employed. When meroury or shot is used a metal washer, ring, or disk, F, is also placed within valve E upon the top of the meroury o1 shot, as shown in Figs. 3 und 5. The diameters of said ball F o1 wasber or disk F are greater than the bore of the induction-pipe, so as 110 prevent valve E being forced int0 said pipe by back-pressure. The load or weight F not only stretches or elongates the. vallve E 130 oause it to forun amore perfect seai for opening d but also causes said valve to automatioally teturn to seat (Z whon mised therefrom by hydrostatio pressure of. a oolumn of water flowing into the inducbion-pipe from the waste-pipe ofa wash-basin, &c. When valve Eis so lifted theopening d is unsealed and water from such fixture passes through tbe trap, as indioatod by the arrows. After the passage of the water,

maised from seat d il: may ascendl until it stiikes agaiust: end (l of pipe D. T0 prgvenb the valve being retained in such position by suction in the eduction-pipo D, and thereby la.-r in outline, as shown in Fig. 6. The ball F or disk F is plaeed Within tbe valve E in he acta f molding the latter, while shot; a.nd mercury are passed .into the ball through the usual small opening formed therein. Ehering 0r washer designed t0 be placed upon Lhe top 0f Such mercury 01 shotis also pussed througb said opening, being fi1st split 01 eul: away, however, to admit; 0f such operation. The split; washer and the manner of inserting it; int0 valve E are plainly illustrated in Fig. 4.

In Fig. 7 I have shown amodifiea'tion 0f my invention wherein the body B bas a iateral eduction opening 01 pipe, D. The top plante, B, is secured to said body by meanS 0f flanges fand inclined lugsf, and the valve E is attached to body' B by a, Iink and button orchain, G.

1 have shown and described the loaded elastic valve in connection with traps f0r Washbasins, &c.; but; in is evident that; tl1e same may be advantageouslyemployetl in hydrnulic rams and other like devices where the operating power 01 pressure is normal and not ot' sufficient force to cause a rapid we'ar of t'ne valve E.

The size of body B and that of the valve E are so proporti0ned thac the latter will always return to the outlet 0f the induction-pipe after beim g elevated therefrom.

VVhat I claim is-- 1. A trap having an eduction and an induction pipe, and an elastic valve cmrying a weight 0r load s uitably arranged t0 prevent the valve being forced into the induction-pipe, and 0p- 3 erating by gravity to seal the outlet; ot' the induction-pipe, and rising therefrom to unseal said outlet; bv t;he pressure of a eolumn of Water or otner fluid in said pipe, substanbially as shown and described.

2. A mlve f0r stench-tra-ps, &c., eomposed 0f a rubber ball, E, baving an inclosed loose metal ball, F, the diameter of whieh is less than that of ball E, and yels is of such extent thalzit prevents Ehe ball E being forced through its sea or into the pipe sealed thereby, substantially as shown and deseribed.

3. In combination with body B, having top am! bottsom plates with inmerposed gaskets or packing-rings, a yoke, C, consbructed and arranged t0 hold said parts together, substantially as slwn and described.

4. The combinalion, with body B, t0p aml bott0m plates, B B, and eduction and inducti0n pipes D D, 0f a valve, E, loaded ab F, substantially as shown am]. described.

5. The combination, With body B, top an l bottom platavs, B B, and eduetion and induction pipes D D, 0f a valve, E, loaded at F, and connecting-yoke (J, substantially as shown and described.

In testimony whereof I affix my signature in presence ot' two witnesses.

JOSEPH BENNOR.
